The Philippine president, Benigno Aquino, has warned of a possible terrorist attack during an annual Catholic procession in Manila.
Aquino said several terrorists planning to disrupt the January 9 event have been sighted in the capital.
He said police were attempting to arrest the suspects and disrupt any planned attack.
He could not confirm whether the Al-Qaeda-linked Abu Sayyaf militant group, which has staged deadly bomb attacks in the capital in the past, was involved in the plot.
On January 9 each year, a wooden statue of Jesus Christ, known as the Black Nazarene, is paraded through the narrow streets of Manila from dawn to midnight, attracting tens of thousands of devotees.
